6.8 Lockout Mode
Command: “LOC <n>”, <n> Setting: '0' = Disabled, '1' = Enabled.
Lockout mode is useful for implementing Sub-Programs in a production setup.
Auto-Run Mode: When used in conjuction with the Sub-Program Select programming function (FUN PRI) as
Phase 1, the pump will enter Auto-Run Mode. In this mode, on power up, the Pumping Program will
immediately begin to execute and upon receiving an Operation Trigger input, the Pumping Program will
immediately begin executing the Sub-Program selected with the Expansion Port.
7. Pumping Program
A Pumping Program is simply a pre-defined sequence of actions, or functions, which guarantees consistent and
precise operation of the pump, automatically, and with or without any user intervention. A Pumping Program
can be as simple as continuous pumping at a fixed infusion rate. Or a Pumping Programs could consist of a
pumping rate and direction of pumping for a specified volume, then switch to another pumping rate. Also a
Program can interact with external devices through the TTL I/O connector, make decisions, or stop pumping
for a period of time.
Programs are broken into individual operations called Phases. Each Phase consists of a function that can be a
control function or pumping function. A pumping function, such as ‘RATE’, consists of a pumping rate,
optional “Volume to be Dispensed”, and the pumping direction.
Complex dispensing systems can be designed, involving multiple liquids, each dispensed from a different
pump, plus other equipment and sensors. Pumping Programs can be designed for each pump which enables
multiple pumps to synchronize with each other, and the other equipment and sensors, using a cable connected
to the TTL I/O connectors of each pump.
When the Pumping Program is started, either from the keypad, TTL I/O connector, or from RS-232, the
Pumping Program will begin with Phase 1 of the Program. After the completion of each Phase, the pump will
immediately start the next consecutive Phase. This linear sequence of Phases can be altered by certain
functions that direct the Pumping Program to continue operation with a different Phase number. Some
functions can change the order of operation conditionally based on external events.
7.1 How to Enter Pumping Programs
A Pumping Program can be uploaded from a computer using PUMPTERM software. A Pumping Program can
be stored in a text file and edited with any word processor, which facilitates development and maintenance of
the program. A Pumping Program generator spreadsheet is available to assist in developing a Pumping
Program and to create the text file for uploading to a pump.
Start by organizing your pumping requirements into specific actions and conditions that can then be
programmed into Phases. For more advance programming methods, common groups of Phases can be grouped
together and repeated multiple times using looping and jump functions.
The current values of the pumping rate, optional “Volume to be Dispensed”, and pumping direction, all refer to
the currently selected Phase. Use the command "PHN" to set the current phase.
To change the “Program Function” of the currently selected program phase, use the "FUN" command. When
finished sending the data for the current Phase, use the "PHN" command to select the next program phase to be
set. Now all pumping data will refer to next currently selected Phase. Data for the current Phase can now be
entered.
Continue selecting Phase numbers and entering the infusion or control setup for each Phase of the Pumping
Program. The entire Pumping Program will be stored in non-volatile memory.
Use the ‘STOP’ function (FUN STP) to stop the pump and end the Pumping Program. If the Pumping Program
does not operate the pump continuously, the last Phase of the Pumping Program must be a ‘STOP’ function
(unless the last Phase number is the maximum Phase number).
